So abundant and so manifold is this life of the astral plane that at first* it is absolutely bewildering to the npophyte ; and even for the more practised investigator it is no easy task to attempt to classify and to catalogue it. If the explorer of some unknown tropical forest were asked not oftly to give a full account of the country, through which he has passed with accurate details of its vegetable and mineral productions, but also to state the genus and species of every one of the myriad insects, birds, beasts, and reptiles which he had seen, he might well shrink appalled at the magnitude of the undertaking : yet even this affords no parallel to the embarrassments of the psychic investigator, for in his case matters are further complicated, first by the difficulty of correctly translating from that plane to this the recollection of what he has seen, and secondly by the utter inadequacy of ordinary language to express much of what he has to report.
